一、引言韦斯汀豪斯模拟式制动机是一种现代化的电子控制式车辆空气制动机,利用列车导线中电流的变化,可以达到快速制动和快速缓解的目的。它特别适用于摩托车组,由于牵引控制也采用同样方式,因此可用一个司机控制器或用列车自动控制系统,既可操纵制动系统,又可操纵牵引系统。该系统可以采用多种方式,但最普通的是装设从列车头部拉向尾部再反回到头部的连续回路导线。制动时,由司机控制器向导线发送不同的电流,当列车导线中的电流增加时,制动机就缓解;电流减小时,就实行 I. INTRODUCTION Westinghouse analog brake is a modern electronically controlled vehicle air brake. The purpose of rapid braking and quick release can be achieved by utilizing the change of current in the conductor of the train. It is particularly suitable for motorcycles, because the traction control is also the same way, so you can use a driver controller or automatic train control system that can operate the brake system, but also control the traction system. The system can take a variety of ways, but the most common is the installation of a continuous loop of wire drawn from the train’s head toward the tail and back to the head. Braking, the driver controller to the wire to send different currents, when the train conductor current increases, the brake to ease; current reduction, it is implemented
